Andy Murray on the up despite Novak Djokovic's Miami triumph
Andy Murray pledged to step up his fight for full fitness after last night's 7-6 (7-3) 4-6 6-0 defeat to Novak Djokovic in the final of the Miami Open.
Murray appeared to run out of steam in the deciding set as Djokovic powered towards the title.
But the Scot has risen to number three in the world despite losing, while the world number one clinched his fifth Miami title, taking his winning record against Murray to 18-8.
"It has been a good start to the year for me so far," said Murray.
"I'm not quite there where Novak is at, but I feel I am getting there. I just need to keep working hard.
"I want to thank the crowd for the atmosphere on court here, sorry I couldn't make more of a fight of the final set. My legs were just hurting and I couldn't quite do it."
Djokovic paid tribute to Murray's battling qualities.
He then added: "I want to thank my team for hanging in there through good and bad times. Thank you Mr Boris (Becker) for joining the club.
"This is one of the best tournaments on the calendar with lots of options both on and off court and I hope it continues for many years to come."
World number one Serena Williams hammered Spain's Carla Suarez Navarro 6-2 6-0 to win her eighth Miami Open title.
Williams (33) said: "I'd like to believe the older I get, the better I get."
